Description

Technical Field

[0001] This utility model relates to the field of resonator processing technology, and in particular to a resonator processing device. Background Technology

[0002] Fused silica hemispherical resonator is a thin-walled cup-shaped component. As a core component of the hemispherical resonator gyroscope, its machining accuracy and surface roughness directly affect the gyroscope's precision. Currently, the mainstream and widely accepted machining method is one-time molding to ensure overall component precision. While one-time molding has its advantages—high machining accuracy and good batch stability—existing technologies rarely allow for simultaneous machining and polishing on the same machine. If the component's precision is to be consistently within 1µm, and the surface roughness within 15nm, the mainstream approach is still to machine on one machine and then polish it on another, typically using multi-axis horizontal grinders or multi-axis vertical grinders.

[0003] The main reason why it's impossible to perform both machining and polishing on the same machine is that the grinding fluid and polishing fluid cannot be mixed. Traditionally, to achieve both machining and polishing on a single machine, two separate circulation systems must be installed. The biggest drawback of this approach is that the two systems cannot be completely isolated, leading to the polishing fluid gradually mixing with the grinding fluid. This results in suboptimal polishing performance after prolonged use, difficulty in cleaning the water tank, damage to pumps and other accessories, and a significant reduction in the machine's lifespan. Utility Model Content

[0004] To overcome the drawback that the outer spherical surface of a resonator cannot be directly polished inside the machine after it has been formed on the same equipment, this utility model provides a resonator processing device.

[0005] The technical solution of this utility model is as follows: a resonator processing device, including a turntable, a fixture base, and a fixture. The turntable includes a fixed frame and a rotation source. The fixture base is connected to the rotation source, and the fixture is set on the fixture base for clamping the resonator rod material. It also includes a bearing, a polishing box, and a connecting block. The bearing is sleeved on the fixture base, and a bearing sleeve is sleeved on the outer ring of the bearing. The polishing box is a semi-closed structure formed by a bottom wall and a side wall, with the end away from the bottom wall being an open end. The side wall has a groove and a notch that allows the polishing tool to extend into the box. The open end of the polishing box is detachably mounted on the bearing sleeve through a snap-fit ​​structure. The open end of the polishing box always faces vertically upward. The bottom of the connecting block is set on the fixed frame, and the front end of the connecting block is inserted into the groove to restrict the rotation of the polishing box.

[0006] As a preferred technical solution of this utility model, the snap-fit ​​structure includes a snap-fit ​​block portion disposed on the outer ring of the bearing sleeve and a snap-fit ​​groove portion disposed in the polishing box, wherein the snap-fit ​​block portion and the snap-fit ​​groove portion are snap-fitted together.

[0007] As a preferred technical solution of this utility model, the clamp includes a collet and a pressure cap. The pressure cap is connected to the clamp base by a thread. The collet is disposed between the pressure cap and the clamp base. The collet has a certain range of extension and retraction. After the resonator rod is inserted into the collet, tightening the pressure cap will cause the collet to contract, thereby clamping the resonator rod.

[0008] As a preferred embodiment of this utility model, the collet's shrinkage range is within 1 mm.

[0009] As a preferred technical solution of this utility model, a first retaining ring is provided between the bearing sleeve and the fixture base, and the first retaining ring is used to prevent the bearing sleeve and the fixture base from directly rubbing against each other.

[0010] As a preferred technical solution of this utility model, the clamp base is provided with a retaining ring, which is located on the outside of the bearing sleeve and is used to restrict the movement of the bearing sleeve and the bearing along the axial direction of the clamp base; a second retaining ring is provided between the retaining ring and the bearing sleeve to prevent the retaining ring from directly rubbing against the bearing sleeve.

[0011] As a preferred embodiment of this utility model, both the first retaining ring and the second retaining ring are made of non-metallic material with smooth surfaces.

[0012] As a preferred embodiment of this utility model, the inner wall of the open end of the polishing box has a concave shape along its radial direction, and an annular sealing gasket is provided in the concave shape, which forms a seal between the inner wall of the polishing box and the outer wall of the bearing sleeve.

[0013] Beneficial effects:

[0014] 1. This utility model installs a detachable polishing box on the bearing sleeve and restricts the polishing box to rotate synchronously with the bearing sleeve by setting a connecting block. After adding polishing liquid into the polishing box, polishing can be performed. This process does not require an additional polishing liquid supply system and will not mix with cutting fluid. Furthermore, after polishing, the polishing box can be disassembled and the polishing liquid can be recycled.

[0015] 2. The outer ring of the bearing sleeve and the groove inside the polishing box of this utility model are clamped by rotation, and the polishing box is further restricted by the connecting block to ensure the stability of the polishing box, avoid loosening or falling off during processing, and improve the safety and reliability of the equipment.

[0016] 3. The threaded connection design of the collet and the pressure cap of this utility model allows the clamp to shrink within a certain range, making it convenient to clamp resonator rods of different diameters, thus improving the applicability and flexibility of the equipment.

[0017] 4. This utility model can effectively prevent friction, reduce equipment wear, and extend service life by setting the first and second retaining rings. The addition of a retaining ring can further prevent the bearing, bearing sleeve, etc. from shifting or slipping during rotation.

[0018] 5. This utility model can form a good seal between the polishing box and the bearing sleeve by setting a sealing gasket, preventing liquid leakage and preventing polishing liquid from entering the bearing gap and causing the bearing to rust. Attached Figure Description

[0024] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that the invention will be more comprehensive and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0025] Although relative terms such as "up" and "down" are used in this specification to describe the relative relationship of one component of an icon to another, these terms are used only for convenience, such as according to the orientation of the examples shown in the accompanying drawings. It is understood that if the icon's arrangement is flipped so that it is upside down, the component described as "up" will become the component described as "down". Other relative terms such as "high", "low", "top", "bottom", "left", and "right" also have similar meanings. When a structure is "up" of another structure, it may mean that the structure is integrally formed on the other structure, or that the structure is "directly" disposed on the other structure, or that the structure is "indirectly" disposed on the other structure through another structure. The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0026] refer to Figure 1 and Figure 2 The resonator processing apparatus shown includes a turntable 12, a fixture base 10, and a fixture. The turntable 12 includes a fixed frame and a rotation source. The rotation source is mounted on the fixed frame; in this embodiment, the rotation source is a motor, and the motor housing is fixed to the fixed frame with the rotating shaft extending forward. The fixture base 10 is connected to the rotation source, and the fixture is mounted on the fixture base 10 to hold the resonator rod 2. The rotation source drives the fixture to rotate and, in conjunction with a processing tool, processes the resonator rod 2 to form its shape. The shape of the processed resonator rod 2 can be referenced. Figure 2 and Figure 4 The structure shown in the figure has a relatively rough surface with many burrs after processing and forming, so the outer wall of the resonator rod 2 needs to be further polished.

[0027] Therefore, based on the above, this device also includes a bearing 8, a polishing box 1, and a connecting block 11. The bearing 8 is sleeved on the fixture base 10, and a bearing sleeve 7 is sleeved on the outer ring of the bearing 8. Specifically, the inner ring of the bearing 8 is fixedly connected to the outer ring of the fixture base 10, and the inner ring of the bearing sleeve 7 is fixedly connected to the outer ring of the bearing 8. The polishing box 1 is a semi-enclosed structure formed by a bottom wall and a side wall, with the end away from the bottom wall being an open end. The side wall of the polishing box 1 has at least one groove and a notch that allows the polishing tool 13 to extend into the box. The open end of the polishing box 1 is the mounting end, which is detachably mounted on the bearing sleeve 7 through a snap-fit ​​structure. It should be noted that the open end of the polishing box 1 is always vertically upward, so that polishing is satisfied while the polishing liquid does not leak out along the notch. The bottom of the connecting block 11 is set on the fixed frame, and the front end of the connecting block 11 is inserted into the groove to restrict the rotation of the polishing box 1. Thus, when the rotating source drives the resonator bar 2 to rotate, the polishing box 1 is restricted to a fixed position and angle and does not rotate synchronously with the bearing sleeve 7.

[0028] This device uses a detachable polishing box 1 mounted on a bearing sleeve 7, and a connecting block 11 to restrict the polishing box 1 to rotate synchronously with the bearing sleeve 7. After adding polishing fluid to the polishing box 1, polishing can be performed. This process does not require an additional polishing fluid supply system, nor does it mix with cutting fluid. Furthermore, after polishing, the polishing box can be disassembled, and the polishing fluid can be recycled. This device can perform both machining and polishing processes on a single machine without the need for two separate fluid supply systems.

[0029] It should be noted that the polishing box 1 can be square, cylindrical, or other similar shapes, such as... Figure 3 As shown, in this embodiment, the polishing box 1 is a cylindrical structure with one end open. A notch is cut into the side wall of the cylindrical structure using a plane parallel to the cylindrical structure. The removed part is generally no more than half of the whole, and the open end is not cut through to ensure the integrity of its annular structure.

[0030] After polishing box 1 is installed, it should be Figure 1 As shown in the diagram, the jig holds the resonator rod 2 inside the polishing box 1, with the notch of the polishing box 1 facing vertically upwards. The polishing cutter 13 extends downwards into the polishing box 1 to contact the rotating resonator rod 2 and complete the polishing process.

[0031] like Figure 3 As shown, the snap-fit ​​structure includes a snap-fit ​​block 14a located on the outer ring of the bearing sleeve 7 and a snap-fit ​​groove 14b located inside the polishing box 1. The snap-fit ​​block 14a and the snap-fit ​​groove 14b cooperate to achieve a snap-fit. In addition, a recess 16 is formed radially on the inner wall of the open end of the polishing box 1. An annular sealing gasket 15 is provided in the recess 16. The annular sealing gasket 15 forms a seal between the inner wall of the polishing box 1 and the outer wall of the bearing sleeve 7, thereby preventing polishing fluid from leaking into the gaps of the bearing 8, which would not only damage the bearing but also waste the polishing fluid.

[0032] Specifically, in this embodiment, multiple locking blocks 14a are arranged along the outer circumference of the bearing sleeve 7. Similarly, locking slots 14b are arranged along the inner circumference of the open end of the polishing box 1. The number of locking slots 14b is the same as the number of locking blocks 14a. In addition, a first retaining ring 9 is provided between the bearing sleeve 7 and the fixture base 10. The first retaining ring 9 is used to prevent direct friction between the bearing sleeve 7 and the fixture base 10. The first retaining ring 9 is made of a smooth non-metallic material.

[0033] refer to Figure 1 , 2The fixture specifically includes a collet 4 and a pressure cap 3. The pressure cap 3 has an internal thread on its inner side, and the fixture base 10 has an external thread on its outer side. The pressure cap 3 and the fixture base 10 are connected by threads. The collet 4 is located between the pressure cap 3 and the fixture base 10. The collet 4 has a certain range of extension and retraction. In this embodiment, the maximum contraction of the collet 4 is within 1 mm. After the resonator rod 2 is inserted into the collet 4, tightening the pressure cap 3 will cause the collet 4 to contract, thereby clamping the resonator rod 2. This fixture is easy to use, and the installation and removal of the resonator rod 2 are very convenient.

[0034] Furthermore, it is particularly important to note that a retaining ring 5 is provided on the fixture base 10. The retaining ring 5 is located outside the bearing sleeve 7 and is used to restrict the movement of the bearing sleeve 7 and bearing 8 along the axial direction of the fixture base 10. A second retaining ring 6 is provided between the retaining ring 5 and the bearing sleeve 7. The second retaining ring 6 is made of a smooth non-metallic material. By providing the retaining ring 5, the sliding displacement of the bearing sleeve 7 or bearing 8 along the fixture base 10 due to centrifugal force during rotation can be further restricted.

[0035] The above embodiments only illustrate preferred embodiments of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications, improvements, and substitutions without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the appended claims.
